ST. PAUL (MNN) – The recent extended stretch of 90-degree heat has caused an increase of blue-green algae in Minnesota lakes.

The Minnesota Pollution Control Agency says the lack of rain also has accelerated the growth of the algae.

Lakes and ponds in Minnesota typically see this much algae in August, not June.

Typically algae found on lakes is harmless, but blue-green algae can be harmful to pets and young children.

Blue-green algae often has a neon glow or can look like greenish bundles or grass clippings.
